STOP MECHANISM FOR TALKING MACHINES.

Application filed Zlune s,

I To (ZZZ whom it may concerm'f Be it known that 1, JOHN E. RENHOLDT,

a citizen of the United States of America,

and a resident of Bridgeport, Connecticut, have invented a new and useful Improvement in Stop Mechanism for Talking Ma chines, which invention is fully set forth in the following specification.

This invention relates to stopmechanism, and particularly to stop mechanism especially designed for use in talking machines.

In machines of the latter type, a sound box operatively connected to a sound-com veying member, which together will be referred to as a traveling element, hasIrelative movement to a rotary record support, which support, or any other suitable rotary member in the drive of said support from the motor of the machine, will-be hereinafter referred to as a rotating element, the soundboX and sound-conveying member generally being. fed across the record-support by the coaction of the former with the groove in the sound-record tablet. It is an object of this v invention to provide stop mechanism of improved construction which will stop the rotation of the record-support or other rotating element upon the completion of the traverse of the sound-box and soundconveying member. y

A further object of this invention is to provide stop mechanism of the character referred to with improved means whereby a predetermined number of revolutions of the rotating element must occur before said stop mechanism can come into action, whether the traveling element be stationary or not.

A. still further object of the invention is to provide a stop mechanism of the type characterized with means for throwing the same out of operation at will to the end that the machine may be controlled solely by the operation of manual means.

Yet another object of the invention is to provide a stop mechanism of the type in question wherein one of the two members respectively moved by the traveling and rotating elements is moved into coacting relation with the other of said members by movement of one of said elements.

Other objects relate to the provision of a i stop mechanism of the type referred to which is simple in construction, inexpensive 1918. Serial No. 238,550.

to manufacture and install, and efficient in operation.

Stated broadly, the invention comprises, in combination with a rotating element and a traveling element, stop mechanism, means for automatically actuating said stop mech- 0 anism upon the stopping of the traveling element, and means for rendering said automatic means inoperative at will. In the preferred construction, said stop actuating mechanism comprises coacting members, shown as under the control of the traveling and rotating elements respectively, and means, shown as driven by the traveling element, for moving one of said members into coacting relation with the other of said inembers. Means are also preferably provided whereby said members assume a coacting relationship only after a predetermined number of revolutions of the rotating element, such means being shown as comprising a member intermittently advanced by timing mechanism into operative positionto moveone of said first-named members into coacting relation with the other of said members. Said stop-actuating mechanism, in the form shown, comprises a member moved by the traveling element, a member oscillated by the rotating element. an intermediate member oscillated by the second member and adapted to coact with the first member to effect the actuation of the stop mechanism, and means to position said intermediate member so that the oscillations of said second member will move said first member.

The invention is capable of receiving a variety of mechanical expressions one of which is shown on the accompanying drawings, but it is to be expressly understood that the drawings are for purposes of illustration only and are not to be construed as a definition of the limits of the invention, reference being had to the appended claims for that purpose.

In said drawings, wherein the same reference characters are used to designate corresponding parts in the several figures,-

Fig. 1 is a top plan view of a talking machine embodying the present invention, parts being broken away to show parts positioned therebeneath Fig. 2 is a side elevation;

Fig. 3 is a bottom plan view;

Fig. 4 is a sectional elevation on an enlarged scale;

Fig. 5 is a perspective view of the elements of the stop mechanism;

Fig. 6. is a transverse section on the line 66 of Fig. 4;

Fig. 7 is a perspective view of the neutralizing pawl;

Fig. 8 is a perspective view of the cam member;

Fig. 9 is a transverse section on an enlarged scale, on the line 9 9 of Fig.1; and Fig. 10 is a detail view of the brake element.

Referring in detail to said drawings, 1 designates a motor of any suitable construction. WVhile in the embodiment illustrated on the drawings the motor is shown as a spring motor, it is to be expressly understood that the invention is of equal utility when applied to a machine driven by an electric motor. The motor 1, through suitable gearing, drives the spindle 2 oi? the usual rotary record-support 3 which carries the record-tablet 4. Mounted for coaction with the record-groove of said tablet 4 is the usual or any suitable sound-box carrying a suitable stylus 6, said sound-box being supported on a sound-conveying member or tone-arm 7 of any suitable construction. In the form shown, said tone-arm T is bent laterally at 8 and journaled for vertical movement on an elbow 9 which is rotatably supported in a collar 10 of a tone-arm support 11,here shown as integrally connected with the motor-board 12.

In the form illustrated, the shank 13 of said elbow 9 extends within the collar 10 below the plane of the motor-board 12and has suitably connected thereto adjacent its lower c'nd a cam member 14 comprising collar 15 for embracing said shank 13 and a cam portion 16 connected to said collar 15. Cam portion 16 is provided with a face 1 concentric with the axis of rotation of the tone-arm elbow 9 and an inclined face 18 for a purpose that will hereinafter appear. The portion of collar 10 protruding below the plane of the motor-board 12 is suitably cut away. as shown at 19, to permit of movement of the cam member 14 with the tonearm 7 through suitable are.

Tone-arm support 11, in the form. shown;

is hollowed out at its underside at 20, and rectilineally movablewithin the recess thus provided is a slide 21 suitably supported from the tone-arm support, as by headed screws 22 received through elongated slots 23in the slide 21. Pivotally supported from the slide 21 is a lever member 24, said slide being provided with a depending boss 25 on which said lever member is pivotally received and retained by a screw 26. Said boss also carries between the member 24 and the head of the screw 26 a cam bushing 27 cam faces on member 14. To maintain cam bushing 27' in cooperative relation with said cam faces, a spring 28, attached at one end to a lug 29 on the slide 21 and at its opposite end to a lug 30 projecting downwardly from the tone-arm support 11, normally urges said slide and the member 24 in the direction of cam member 14. Member 24 at its outer end is provided with a transverse head portion 31 shaped to provide two or more projections 32 and 33 respectively. In the form shown said projections are provided by cutting notches in the edge of said head portion 31.

Suitably mounted on the turn-table spindle 2 is a knurled collar 34, the same being shown as retained in position by the setscrew 35. Mounted for cooperation with said knurled collar 34 is a knurled eccentric 36, the same being supported in any suit able way, as by a screw 37, from an oscillating member 38. While, in the form shown, the collar 34 and eccentric 36 have been provided with knurled surfaces, it is to be expressly understood'that such is not essential, as any other suitable friction surfaces could heemployed instead, or said collar and eccentric might be provided with gear teeth. Member-38 is mounted for rectilinear oscil lation in any suitable way, as by supporting the same between bosses 39 on the motorf ame 40 and headed screws 41 extended through elongated slots 42 in said oscillating member. To, normally maintain eccentric 36 in cooperative relation with said collar 34, the oscillating member 38 is normally urged toward said collar by a spring 43 attached at one end to saidoscillating member 38 and at its opposite end to a pin 44 projecting upwardly from the motor-frame. Pivotally mounted on the outer end of oscillating member 38 is an arm 45, the same being shown as pivoted to the member 38 by a screw 46 between the head of which and said arm is a spring washer 4'? for preventing too free movement of said arm. Arm 45 at its outer end is provided with an upstanding. lug 48 designed for engage inent withthe projections 32 and 33 as will be explained hereinafter.

Pivoted at 49 to the side of the oscillating member 38 is a pawl 50 provided with-a tooth 51. Mounted for rotation on the motor-frame 40 is a ratchet gear 52 the teeth of'which are in the path of oscillation of tooth. 51 on pawl 5O as the latter is carried backward and -forward with the oscillating member 38. Gear 52 is a mutilated gear to provide a blank space at 53 for a purpose to be hereinafter explained. Said gear is mounted for rotation in any suitable way, as by a screw 54, and between the head of said screw and said gear is shown a coifed spring 55 to prevent too free rotation of said gear. Gear 52 also carries an upstanding member 56 designed to engage and position the lug 48 on arm for coaction with the projections 32 and 33 on member 24. 1

Also pivoted on the motor-frame at 57 is a stop-actuating member 58-provided at its outer end with an upstanding lug 59 in the path otmovement of head'31 on member 24. Member 58 also carries adjacent its outer end a pawl 60 pivoted to said member at 61 and provided at one endwith an arm 62 which is normally held. in engagement with lug 59 by a spring 63. At its opposite end said pawl 60 is provided with a tooth 64"adapted to engage a tooth of the mutilated gear 52 and rotate said gear.

Any suitable stop mechanism may be operated by said stop-actuating member 58. In the form shown, a brake device 65 is carried by an arm 66 depending from the member 58 in position to engage the usual triction disk 67 of the governor mechanism. It is to be expressly understood, however, that said brake device by suitable variation may be made to engage and brake any other suitable rotating element or, if the motor be electric, be made to operate a suitable switch mechanism, In the structure illustrated, said brake device comprises a brake pad 68 supported in a carrier 69 which may have a limited rectilinear movement in a shell 70 suitably mounted in said arm 66. A'spring 71 in said shell 70 between'thehead of the carrier 69 and a screw 72 normally urges the brake pad to its outermost position and cushions the shock of engagement thereof with the element braked;

Any suitable device for moving the stop mechanism into and out of starting position be employed. In the'form shown, a bell-crank lever 73 is pivoted at 74 to the motor-frame and has at one end an upstanding lug'7 5 designed to engage in a slot 76 provided in the end of stop-actuating member 58. The opposite end of said lever 73 extends, as shownat 77, to a position outside the periphery of the motor-board where it maybe conveniently operated. Means are also provided for retaining the starting lever 73 and stop-actuating member 58 in the starting position and for moving said members to stopping position after initial actuation of the same. Such means may take the form of a toggle spring connected to and movable across the point'ot engagement of members 73 and 58, or, as illustrated on the drawings, lever 73 may be provided with a ridge 78 for frictional engagement with a plate 79, a springBO, attached at one end'to said plate and at its opposite-end to a suitably mounted screw, 81, urging said members 73 and 58 to stopping position as soon as the end of ridge 78 passes out of engagement with plate 79, 7

it is frequently desirable to render' the automatic stop-actuating member inoperative so that the machine maybe stopped solely by manual operation of the stop-actuating members. To this end a neutralizing pawl 82 is pivotally mounted, as by a screw 83, on the motor-board 12, said neutralizing pawl being shown as provided with a hub 84 for receiving the lower end of said screw. Said pawl is provided with a pair of stop lugs 85and 86 and an upstanding finger 87 7 5 which may be moved into the path of oscillation of pivoted arm 45. To retain the pawl in the position to which it is adjusted, a spring 88 is received between the hub 84 and the motor-board under sufficient tension to retain said pawl in whichever position it may be placed."v Screw 83 is shown provided with knurled operating head 89 to facilitate the adjustment of the pawl, and a stop 90 suitably connected-to the motoras board depends into the path of the lugs 85 and 86.

Operation: Assume first that the neutralizing pawl is in the position shown in full lines in Fig. 1 wherein the upstanding finger no 87 is out of the path of oscillation of the arm 45. The machine is started by moving the projecting 'end 77 of lever 73 from its extreme left-hand position to its extreme right-hand position as shown in Fig. 1. During this movement, lug 75 on lever 73, by engagement with the wall of the slot 76 in member 58, causes the latter to move in a clockwise direction about its pivot 57 whereby the arm 66 withdraws brake device 65 from engagement with the governor disk 67. This movement of lever 73 also brings ridge 78 into engagement with plate 7 9, moving the latter against the tension of spring 80, and the frictional contact of said ridge and plate is sufficient to retain the lever 73 and stop-actuating member 58 in the starting position. Motor 1 now begins to rotate the spindle 2 and record-support 3.

Cam member 14'is mounted on the shank 13 of tone-arm elbow 9 so that the inclined face 18 is in engagement with cam bushing 27 when the tone-arm and sound-box are to one side of the record-support'3 and'also, preferably, when the sound-box is at the be- 115 ginning of the record-groove, say of the usual ten-inch record-tablet, Reproduction is started by moving thestylus 6 of the sound-box 5 into engagement with the groove of the record-tablet '4. During the 120 initial advance of the tone-arm, cam member 14, which rotates with the tone-arm elbow 9, moves its inclined face 18 out of engagement and its concentricjface 17 into engagement with the cam bushing 27 During 125 the movement ofinclined face 18: over the cam bushing 27. the slide 21 is moved outwardly against the tension of the spring 28 until the head31 of member 24 is in position to coact at the proper time, with the pivoted 13 armeii and to engage, when the traveling element ceases its traverse, the upstanding lug59 of actuating member 58. Thereafter, theiarcuate face 17 of cam member 14: rides over the cam bushing 27 without changing theposition of the slide 21.

i W henthe motor starts rotation of the spindle 2, the knurled collar 8 by cooperation with the knurled eccentric 36, oscillates the member 38. Assumingthat'the ratio of members 36 and is two toone, member 38 will be advanced to; the left in Fig. l. at each second revolution oi the record-support. At. each advance of the member 38, pawl 50 engages'its tooth 51 with one of the teeth of the ratchet gear 52, advancing the latter through the space of one tooth. Assuming, for purposes oi illustration only, that there are tom-teen teeth on the ratchet gear 52, it will therefore take twenty-eightrevolutions oi the turn-table spindle 2 before a full rotation of the ratchet gear 52 is completed. During the period that said gear is making its rotation, arm to is free to rotate on its pivot l6 and. even if at the beginning of the oscillations of the member 38 the: lug l8 on said arm 45 should contact head 31, said arm will simply be moved freely on its pivot 4:6 in an anticlockwise direction. Nhen gear 52 has made a complete rotation, however, the upstanding member 56 is brought into. the path of movement of arm liand said arm is thereafter maintainedin position for coaction with the projections 32 and on head 31, as the mutilation 53 on the gear is now in the path of oscillation OTE tooth 5t.

on pawl 50 and'52 is no longer advanced intermittently by said pawl.

Member 241 is in effect a lever pivoted. on the boss 25. At the initialmovement of the tone arm into cooperative relation with the record-support, the clockwise rotation ol cam member 1l by engagement with the bushing 27 causes the lever membcr2e to move on its pivot 25 in an anticlockwise direction to the limit defined by any suitablestop such, for examplmas the wall ot the slot in the tone-arm support 11 through which said member projects.- After member 56 has been advanced through its complete rotation and into the position shown in Figs. 1 and 5, arm 4C5 is maintained by said .member in such a position that movement 0t direction, until lug on arm 45, positioned by member 56, again engages projection during-the, next forward movement of mem-. ber 38 and moves said member 24; in a clockwise direction.

As long as the tone-arm continues. its traverse, lever member 24 is thus moved backward and forward through a slight arc owing to, the alternate and intermittent action of the cam member- 1a and arm 45 on its opposite ends, it beingunderstood that while the arm lo is moving said member 24- ina clockwise direction the cam bushing 2? slides freely over the face 17 of cam member 14. lVhen, however. the tonearm ceases its traverse, lever member 2a is no longer subjected to a force tending to move the same in an anti-clockwise direction. Therefore, following its movement into approximate stop-actuating position by engagement therewith of arm as it retains such position and, upon the next advance of arm 45, the upstanding lug 48 engages the second projection 33 on head 31 and said head is thereby moved into final stop-actuating position, engaging and moving the upstanding lugv 59 on member 58,

Movement of lever member 58 by engagement of head 31 with upstanding lug 59 causes lever 73, through the cooperation of lug and slot76, to move in a clockwise direction until the end of ridge 78 passes out of engagement with plate 7 9, whereupon the spring 80 quickly throws members 73 and 58 into stopping position, wherein brake pad 68 engages governor disk 67 and stops the machine, the shock of the engagement being absorbed by the spring 71. During; this movement of member 58, pawl (30 engages its tooth 64 with one of the teeth on gear 52crotating the latter gear so as to withdraw space 53 trom'the path of tooth 51 and advancing a tooth on said gear into position forengagementby tooth 51 when the machine is next started.

In case it be desired to throw the automatic stop mechanism out of operation so that the machine can be stopped solely by manual actuation of lever 73, the neutralizing pawl 82, which has stood with its lug 86 in engagement with stop 90, is moved by rotation of knurled head 89 until lug engages said stop 90, in which position the. upstanding finger 8'? on said pawl is ad vanced into the path of movement of the lug 48 on arm 4.5. It, now, the machine is started, said finger 87 will receive the thrust of the arm 45 just before lug 48 can engage a projection on thehead 31, even after the member 56 has completed its rotation and is in the position shown in Fig. 5, Member 24:, therefore, can receive no impulse to move the. same into engagement with lug 59 on member 58, and the motor will continue to run. until lever 73 is moved in a Ill) illustrated on the drawings has been described with considerable particularity, it
